SHOCK-FORMING DEVICE.

Application filed April 9, 1918, Serial No. 227,546.

T 0 all whom it may concern Be it known that 1, ANDREW H. PALM- BUSH, a citizen of the United States, residing at Conrad, in the county of Teton and State ofMontana, have invented certain new and useful Improvements in a Shock-Forming Device, of which the following is a specification. o This invention relates to improvements in harvesting apparatus and it is the principal object of the invention to provide a device for receiving sheaves from a binding mechanism and arranging the same, then deposit them on the field or other surface in shock form, thus, obviating the necessity of gathering the sheaves discharged from the binding mechanism and shocking the same manually; hence, efi'ecting a material saving in time and labor.

Another and equally important object of the invention is to provide the device with a novel form of basket or former for receiving the sheaves and arranging the same to constitute the usual shock on the field over which the device is moving when a predetermined number of sheaves have been deposited therein from the binding mechanism.

Other independent objects are to provide features of construction of portions of the device which tend toward the attainment of the aims irrespective of the relation in which they are used.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction hereinafter set forth and the scope of the application of which will be indicated inthe following claims.

In the accompanying drawings, wherein is shown one of various possible embodiments of my invention:

tive showing the mounting of the former carrying shaft.

Having more particular reference to the drawlngs, in connection with which like reference characters will designate corresponding parts throughout the several views, 1 represents the frame of the device, the same being substantially triangular in shape and mounted upon suitable wheels, not shown. An endless conveying belt 2 is mounted on the usual pulleys journaled in bearings in the opposite ends of the inclined portion of the frame 1 and as will be understood, is arranged to communicate with the sheaf receiving and discharging basket arranged on a binding mechanism to which my improved device is attached.

In order that motion may be transmitted to the endless belt conveyer 2, the shaft carrying the lower pulley has one end thereof extended as indicated by the numeral 3 and has interengageable clutch elements 4 and 5 loosely mounted thereon, the slidable clutch element 4 being formed with the usual serrated portions upon each of the ends, one of which is adapted to engage with a pin 6 passing through the extended end 3 of the shaft, While the remaining portion is adapted to be engaged with the adjacent face of the non-slidable clutch elements 5. A sprocket wheel 7 is mounted on the clutch 4 and receives the usualform of sprocket chain, not shown, thereabout, which chain has connection with drive means arranged on the binding mechanism to which the device is connected. The remaining clutch 5 is provided with a form of windlass 8 having one endof a cable 9 secured thereto as at 10, the remaining end of the cable extending forwardly into engagement with a lever, hereinafter more fully described. To normally maintain the clutches 4 and 5 disengaged, an expansible coil spring 11 is inter posed therebetween; the opposite convolutions thereof being arranged against the adjacent portions of the clutches. Slidably mounted on the extremity of the extension 3 is an operating arm 12, which as will be noted, has bearing on a casing sleeve 13 arranged over the clutch element 4. One end of the arm 12 is connected to a link 14 having connection with aportion of the frame 1, while the remaining end thereof is connect- '9 thereabout without actuating ed to an operating cable 15 passing over a suitable pulley 16 arranged on said frame 1 into engagement with operating means mounted on the binding mechanism at a point convenient to the operator. Obviviously when a motion transmitting chain from the binder is operating about the sprocket wheels 7 the conveyer will be in operation but by pulling the cable 15, the arm 12 will be moved inwardly and as a consequence, the clutch 4 will be disengaged from the pin 6 so as to be loose on the shaft extension and engaged with the clutch 5, thus imparting rotary motion to the same and to its windlass 10, and coiling the cable the conveyer.

Arrangedtransversely of the lower portion of the frame 1 is a shaft 17 having arms 18 secured thereto in spaced relation, which arms are pivotally connected to other arms 19 having pivotal connection with the former carrying frame 20. As will be noted, the frame 20 is substantially square and has the rear end thereof pivotally engaged with hangers 21 pivotally connected to the inclined sides of the frame 1, while the for ward portion'thereof is pivotally connected to other hangers 22 which, as will be noted, have pivotal connection with the vertically disposed sides of the frame 1.

Disposed longitudinally of the frame 20 and rotatably mounted inbearings 23 and 23 arranged thereon is a shaft 24, the forward portion of which is flattened and curved slightly in order that the same can be connected to the shock forming element 25 by bolts 26 or similar fastening devices which are passed therethrough into engagement with said flattened end. In this connection, it is to be noted that'the former 25 is secured to the flattened end of the shaft 24: at a point off-center and as a consequence, when the former is filledwith sheaves, the same will be overbalanced and caused to rotate in a direction such as will effect the dis charge of the sheaves therefrom ontothe field or other surface over which the device is moving. To limit rotary motion of the shaft 24-, certain of the ends of the bearings 22 and 23 are notched as at 27 and receive therein cross pins 28 passing through the adjacent portions of the shaft 24.

Fixedly mounted on the interniediateportion of the shaft 24: is a drum 29 having a contractile coil spring 30 arranged thereabout, one end of which is secured to the periphery thereof as at 31 while the remaining endis connected to a cable or like'connection 32 secured to a portion of the former carrying frame 20 as at 33. Hence, when the former 25 is rotated dueto the overbalancing of the same, the shaft 24: will serve to place the contractile spring 30 iuider tension. As a consequence, when the sheaves have been discharged from the former in shock form the same will be immediately returned to its normal position due to the connection of said spring 30 with the drum 29.

The former 25 comprises a substantially cylindrical element having the sides thereof tapered and the upper portion of the same open and formed with upwardly extending flared guides 34, which guides, obviously,

serve as means for directing the sheaves delivered from the binding mechanism into the former. Due to the tapering of the former, the sheaves will be properly arranged and when discharged onto thefield will constitute theusual shock. To prevent the sheaves delivered into th former from falling therefrom, a-gate 35 is provided and is carried upon a substantially horizontally disposed arm 36 arranged on the upper end of a vertically disposed shaft 37, :which as will be noted, is journaled in bearings 38. arranged on one side of the frame 1 and carries an arm 39 upon its lower end, which arm is pivotally engaged by a link 40 having pivotal connection with another arm il'fixedly mounted on the-transversely disposed shaft 17. Hence, when the shaft 17 is rotated, rotary motion will be imparted to the shaft 37 thereby causing horizontal movement of the arm 86 and therebyrmoving the gate 35 out of engagement with the adjacent open end'of the former 25. To prevent V rotation of the former 25 while in a position adjacent the gate 85, a segmental arm 42 is'arranged on one end thereof and'is adapted to be engaged with the upper portion thereof. In this way, it will be understood that the former -will be prevented from rotating until the segmental arm 42 is disengaged from the gate35; 7'

T he operation of my improved device may be reviewed as follows:'

The device is attachedto the usual form of binding mechanism at a point adjacent the sheaf receiving and discharging basket thereof. Power is transmitted to the endless belt 2 by way of the sprocket wheel 7 and the chain arranged thereabout and as a consequence, the sheaves discharged from the sheaf receiving and discharging basket of the binding mechanism will be delivered onto said conveyor and carried upwardly thereby whereupon they will be discharged into the former 25 and properly arranged to constitute the usual shock. When a sufficient number of sheaves have been discharged into the former, the cable 15 is pulled to effect disengagement of the clutch 4L from the shaft extension 8 and to engage the same with the clutch 5, whereupon the cable 9 will be coiled thereabout and as a consequence, the arm 17 will be rocked to cause the frame 20 to move forwardly, then upwardly. At'the same time, the'shaft 37 will be rotated thereby causing the arm 36 and the gate 35 carried thereby to be moved out of engagement with the adjacent open end of the former 25 and also out of engagement with the segmental arm 42 secured thereto. Due to the fact that the former 25 is mounted off-center on the shaft 24, the same will be overbalanced and will rotate to a position whereupon the sheaves will be discharged therefrom onto the field in form of a shock. As hereinbefore stated, rotary movement of the shaft 24 and as a consequence, the former 25 is limited by reason of the engagement of the pins 28 with the notches 27 formed in the adjacent ends of the several bearings 22 and 23. When the sheaves have been discharged from the former, the spring 30 will then serve to rea turn the same to its normal position ready for further operation. Furthermore, after the former 25 has been rotated to its discharging position, the cable 15'is released, thereby causing the clutches 4 and to be disengaged and reestablishing connection between the clutch 4 and the extended end 3 of the shaft carrying the lower pulley of the conveying means. By reason of the disengagement of the clutch 4 from the shaft extension 3, it will be also understood that travel of the endless conveyer beltwill be temporarily discontinued and therefore, sheaves will not be discharged from the same onto the former until the same has returned to its normal position with respect thereto.

Manifestly, the construction shown is capable of considerable modification and such modification as is within the scope of my claims, I consider within the spirit of my invention.
